Importer plugin crashes with 'Critical error'

This plugin used to work, we’ve used it for a couple of years (an annual event), but this year it just crashes. Latest version of WP (6.3.1), latest EE (5.0.10), latest Importer (1.0.3), PHP 7.4.33.
Any ideas??
I noticed a post here from May saying there was an issue with this plugin but v1.0.3 should have resolved that.

Sometimes we get an email (but not always) and the issues mentioned seem to vary.
The last one was:
Error Details

Is it worth re-installing EE and/or the Importer plugins?

We’re trying to replicate your issue on our end, but we’re not able to do it. Can you try Downloading EE plugin and re-installing it?

Also please check if you can import the basic template.
here’s the link

Can you also shoot us video of what happen when you try again. you can use loom to record it

If you can also share the CSV you have, so we can also test on our end, that would be great.

Hi there,

I’ve managed to reproduce this and pushed an update for the importer add-on which should fix it.

If you don’t see an update available for the Importer add-on go to Event Espresso -> General Settings.

Don’t make any changes and just hit save to force an update check.

The update should then show in Dahsboard -> Plugins.

Thanks Tony, the update has resolved the issue … thank you very much, this has saved many hours of tedious imputing!
